Version 0.16 of llm-mistral was released on 6 October 2026 and announced in a short post on Simon Willison's blog. The plugin connects the LLM tool to Mistral models through the Mistral API.

The release note is a single line: it adds support for reasoning models, such as the newly released Mistral Large 4. The post is tagged llm, mistral and llm-reasoning, and links to the 0.16 release page on GitHub (simonw/llm-mistral).

The note gives no further detail. It does not describe Mistral Large 4 (size, pricing, benchmarks or release date), and it does not explain how reasoning support works in the plugin, such as options, parameters or how reasoning output is handled. It also does not say which other Mistral models are now covered as reasoning models. No fuller changelog was available beyond that one line.

Key facts

  • llm-mistral 0.16 was released on 6 October 2026.
  • The release adds support for reasoning models, such as the newly released Mistral Large 4.
  • llm-mistral is a plugin that lets the LLM tool use Mistral models via the Mistral API.
  • The release note is one line; no details on Mistral Large 4 or on how reasoning support is implemented are given.

Why it matters

The update ties the plugin to a fresh Mistral release: its note names Mistral Large 4 as newly released and as an example of the reasoning models it now supports. For people who reach Mistral models through the LLM tool, that is the practical signal here. The post is also tagged llm-reasoning, which places it among the LLM tool's reasoning-model support work. It is a small incremental release, not a major change.

Who it affects

Users of the LLM tool who call Mistral models through the llm-mistral plugin, and in particular anyone who wants to try Mistral Large 4 or other reasoning models from that tool.

How to use it

The note says reasoning models, such as Mistral Large 4, are now supported in llm-mistral 0.16. The text does not give installation or upgrade instructions, so check the release page on GitHub (simonw/llm-mistral, tag 0.16) for details.

How solid is it

The claim is the project's own one-line release note, posted on 6 October 2026 and linked to a GitHub release tag. Nothing in it is independently verified, and it contains no benchmarks, numbers or technical detail to check. A fuller changelog was not available.

Risks and caveats

The note is too brief to say how reasoning support behaves, which options it exposes, or which Mistral models besides Mistral Large 4 it covers. It also says nothing about Mistral Large 4 itself, including pricing or capability, so it should not be read as an assessment of that model.

“Adds support for reasoning models, such as the newly released Mistral Large 4.”
